    3. 3. Contents o Part 1: About World Cancer Research Fund (WCRF UK) and the evidence on lifestyle and cancer risk (slides 3 – 15) o Part 2: WCRF UK’s Recommendations for Cancer Prevention (slides 16 – 38) o Part 3: The role of health professionals, current awareness levels and how WCRF UK can help (slides 39 – 48) 3 3
    4. 4. Part 1: WCRF UK and the WCRF global network 4
    5. 5. About WCRF UK o Our vision World Cancer Research Fund (WCRF UK) helps people make choices that reduce their chances of developing cancer o Our mission To fund research on the relationship of nutrition, physical activity and weight management to cancer risk To interpret the accumulated scientific literature in the field To educate people about choices they can make to reduce their chances of developing cancer 5
    6. 6. Key achievements o 1997 First Expert Report Food, Nutrition and the Prevention of Cancer: a Global Perspective o 2007 Second Expert Report Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective o 2009 Policy Report Policy and Action for Cancer Prevention o 2007 onwards - Continuous Update Project Keeping the evidence current 6
    7. 7. Why cancer? o Cancer is a major cause of death, disability and lost life years o Cancer is mostly environmentally determined and largely preventable o Alongside smoking, food, nutrition, body fatness and physical activity are the most important factors affecting cancer risk o Evidence to support this comes from many different sources o Preventing cancer through food, nutrition and physical activity will also prevent other major chronic diseases
    8. 8. A largely preventable disease o About a third of the most common cancers in the UK could be prevented if everyone ate a healthy diet, was physically active, and maintained a healthy weight o This equates to around 87,000 cases a year, enough to fill the Olympic Stadium! o However, many people feel that cancer is out of their control o And not everyone is aware of what they can do to lower their risk
    9. 9. Non-communicable causes of death UK China Men 9
    10. 10. Age-standardised rates of common cancers UK Men China 10
    11. 11. Migration data 11
    12. 12. Food, nutrition, obesity, physical activity, and cellular processes linked to cancer 12
    13. 13. 13
    14. 14. The evidence behind WCRF UK’s messa o 2007 Second Expert Report o Six years to produce o Involved over 200 scientists o Independent observers, including the FAO, WHO and UNICEF o Examined all the available evidence from around the world 14
    15. 15. The evidence behind WCRF UK’s messa o Initial sweep found half a million studies o Screened down to 7,000 that were relevant and robust o Findings reviewed by an independent Expert Panel of 21 of the world’s top researchers o Only the strongest evidence was used as the basis for WCRF UK’s Recommendations for Cancer Prevention 15
    16. 16. Keeping the evidence current 16
    17. 17. Part 2: WCRF UK’s Recommendations for Cancer Prevention becoming underweight 1. Be as lean as possible without 2. Be physically active for at least 30 minutes every day 3. Avoid sugary drinks. Limit consumption of energy-dense foods (particularly processed foods high in added sugar, or low in fibre, or high in fat) 4. Eat more of a variety of vegetables, fruits, wholegrains, and pulses 5. Limit consumption of red meats and avoid processed meats 17
    18. 18. 6. 7. 8. If consumed at all, limit alcoholic drinks to 2 for men and 1 for women a day Limit consumption of salty foods and foods processed with salt (sodium) Don’t use supplements to protect against cancer Special population Recommendations: 9. It is best for mothers to breastfeed exclusively for up to 6 months and then add other liquids and foods 10. After treatment, cancer survivors should follow the Recommendations for Cancer Prevention And, always remember – do not smoke or chew tobacco 18
    19. 19. Recommendation 1: Be as lean as possible without becoming underweight o A key way to reduce cancer risk – excess body fat increases risk of bowel, oesophagus, pancreas, kidney, endometrium (womb) and breast cancer (in post menopausal women) o Diet based on plant foods and being physically active 19
    20. 20. 20
    21. 21. Recommendation 2: Be physically active for at least 30 minutes every day o Any form of physical activity can help to protect against bowel and breast cancer o And reduce the risk of becoming overweight o The more, the better! 21
    22. 22. 22
    23. 23. Recommendation 3: Avoid sugary drinks. Limit consumption of energy-dense foods (particularly processed foods high in added sug or low in fibre, or high in fat). o Sugary drinks and energy-dense foods are linked to weight gain o Contain more than about 225-275 kcal per 100g o Contain more fat and sugar 23
    24. 24. 24
    25. 25. 25
    26. 26. Recommendation 4: Eat more of a variety of vegetables, fruits, wholegrains, and pulses such as beans. o Aim for at least 5 A DAY! Vegetables and fruits help to protect against a range of cancers o Include wholegrains or pulses with every meal o These foods tend to be less energy dense – help us avoid weight gain o Contain plenty of water and fibre – fibre can help prevent bowel cancer 26
    27. 27. 27
    28. 28. Recommendation 5: Limit consumption of red meats (such as beef, pork and lamb) and avoid processed meats o Red meat and processed meat are both convincingly linked to bowel cancer o Aim for less than 500g cooked red meat a week – choose smaller, leaner portions o Avoid processed meat, like bacon and ham, almost always 28
    29. 29. Portion of red meat Protein alternatives 29
    30. 30. Recommendation 6: If consumed at all, limit alcoholic drinks to 2 for men and 1 for women a day o Alcohol raises the risk of five common cancers o Liver, breast, bowel and mouth and oesophagus 30
    31. 31. What is one drink? A drink is: o half a pint of normal strength beer, lager or cider o one 25ml measure of spirits such as vodka o one small (125ml) glass of wine 31

    33. 33. Recommendation 7: Limit consumption of salty foods and foods processed with salt (sodium) o High-salt diets are linked to stomach cancer o Aim for less than 6g a day – about a level teaspoonful o Most of the salt in our diet comes from processed foods such as bread, cereals, ready meals and sweet foods such as biscuits! 33
    34. 34. 34
    35. 35. Recommendation 8: Don't use supplements to protect against cancer o The best option is a balanced diet o High dose supplements of some nutrients can affect the risk of different cancers o Some people can benefit from taking supplements for other reasons – refer patients to their GP 35

    37. 37. Recommendation 9: It is best for mothers t breastfeed exclusively for up to 6 months and then add other liquids and food. o Breastfeeding can protect mothers from breast cancer o Having been breastfed can protect children from becoming overweight and obese 37
    38. 38. Recommendation 10: After treatment, cancer survivors should follow the Recommendations for Cancer Prevention. o Cancer survivors are people who are living with a diagnosis of cancer o Growing evidence shows physical activity and other measures that help us maintain a healthy weight may help to prevent cancer recurrence o Seek advice from an appropriately trained consultant or dietitian 38
    39. 39. And, always remember – do not smoke or chew tobacco 39
    40. 40. Part 3: What can health professionals do? WCRF/AICR’s 2009 Policy Report: o Multinational bodies o Government o Industry o Health professionals o Schools o Media o Workplaces o Civil society organisations o Individuals 40
    41. 41. The role of health professionals Health professionals are a trusted source of health information. You: o Can give advice on wellbeing and prevention, not just diagnosis and management of disease o Meet people when they are open to and in need of health promotion messages o Take the lead in promoting health to colleagues, other professionals and other actor groups o Be effective in delivering successful behaviour change initiatives 41
    42. 42. Awareness of risk factors YouGov Survey Results October 2012 (2,012 subjects – general public) “Which, if any, of the following do you think increases your risk of getting cancer?” o 88% of people identified smoking o Only 63% identified a poor diet or being overweight o Only 49% of respondents identified physical inactivity as a cancer risk factor o Only 61% identified drinking alcohol
    43. 43. Awareness of risk factors Even fewer – only 45% of respondents – correctly identified processed meat as a cancer risk factor But: 50% identified stress even though the evidence does not suggest that this affects cancer risk
